Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method. The substance is considered to be adequately characterised with its isomers composition. Therefore validation applies, with minor restrictions due to heating rate (accuracy).
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- yes
- Remarks:
- heating rate slightly exceed maximum of 1K/min as recommended
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- heating rate slightly exceed maximum of 1K/min as recommended
- GLP compliance:
- no
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 588 K
- Atm. press.:
- 97.7 kPa
- Decomposition:
- no
- Remarks on result:
- other: =315°C; accuracy +/-2K
- Executive summary:
The boiling point of the test substance was determined according to OECD 103/EU A2 guideline, Siwoloboff (capillary) method. Two main runs were performed, and the mean value was retained. The measured boiling point was 315°C under 97.7 kPa.

Description of key information
Boiling starts between 315 and 322°C (under normal Patm), depending on composition.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 318 °C
Additional information
Two reliable experimental studies, conducted according to a recognized OECD/EC method, are available. Despite minor restriction due to heating rate (accuracy), both are considered as key studies, as relating to two different compositions. The mean result is retained as key data.
